Hi!
The classification is Keter because the trees replicate pretty rapidly (3 days tops). It's also uncontained, for the most part. I've considered downgrading it to Euclid, but I stuck with Keter because it's that much spicier.

Yeah, but... I'm not sure why that is, though. Sure they're hard to uproot or whatever, but they don't even pass basic visual inspection; they're not trees, they're cell towers that have some treelike features, which makes them pretty conspicuous. Even if they were indistinguishable from trees, they would be easy to detect looking at the cell networks (in real life there aren't that many cell towers in one area... So extras would be super obvious, no?).

Even given the anomalous broadcasts, there can't be that many people burying cell phones for the spread to be fast. Especially since most places somebody would bury an object would make the "tree" stand out (a backyard, a park, by the side of the road...). The lady from the logs isn't going deep into the wilderness to hide the tree she doesn't know will grow. So how many are supposedly hidden from foundation view? Actually, wouldn't all of them be coming up very close to people?

Again, this is a very good SCP, but as currently explained, it poses no real danger, it could never rage out of control, and would not be all that difficult to contain. Frankly I'd need a better explanation why this isn't just "safe" after a reasonable effort on the foundation's part, let alone keter.

If you're really married to the idea that they're uncontained for some reason, maybe have the trees not interact with phone networks and look identical to real trees, so the only signs are broadcasts and trees that just don't seem quite right. Or maybe have the reproduction be less dependent on deliberate, unforced, bizarre human behavior, so it's more believable as an exponential threat.

"aliena" sounds more poetic and less prosaic than "aliorum", and "potestas" doesn't really fit, as that's the kind of power/authority bestowed upon someone from office or rank. "vis" is the best fitting general purpose word for "power, force". Try "robur" if you want physical power/brute strength/hardiness.

You can also swap the word order, depending on which prosody you like best:

I listened to this a few weeks ago when it was first posted and i cant get it off my mind. It gives me so much hope because im cursed with a very deep voice. I was wondering if you had any pre-op voice recordings for comparison, i understand if you wouldnt want to share those though.

When I was coming out to my parents, my dad called my mom into the room with the whole "we have something to tell you" kind of thing, and the first words out of my mom's mouth were "What? You're gay?" and I was just screaming internally "you ruined the punchline!"

As a point of feedback, wear your bra a little higher. The people at /r/abrathatfits has a lot of really good tips and pointers. IF your rack looks good, then nobody will pay attention to your shoulders. (Which are also just fine, girl.)
